IMPROVEMENT IN COCKS OR VALVES.

Specification forming part of Letters Patent No. 221,506, dated November 11, 1879; application filed October 1, 1879.

To all whom it may concern Be it known that 1, CHARLES A. BLESSING, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements inCocks or Valves, of which the following is a specification.

This invention relates to certain improvements in cocks or valves; and it has for its object to provide a cook or valve by means of which hot or cold water alone, or mixed in any desired quantities, may be drawn from suitable sources connected with the valve by suitable pipes.

To this end the invention consists of a cas ing provided with two valve-chambers, communicating, by means of separate passages, with hot and cold water supplies, respectively, in combination with two independently-moving valves and suitable mechanism for actuating the same, whereby either cold or hot water alone or both together, mixed in any desired quantities, may be drawn off, as more fully hereinafter specified.

In the drawings, Figure I represents a sectional view of my improved cook or valve. Fig. II represents a top view of the upper valvedisk; Fig. III, a similar view of the lower valvedisk; and Figs. IV, V, and VI, diagrams showing the relative positions of the valves and ports for drawing oft cold water, cold and hot water mixed, and hot water alone.

Referring to the drawings, the letter A designates the valve-casing, provided with two passages, a I), which may be connected, respectively, with cold and hot water supplies. The said casing is provided with two valvechambers, c d, which communicate, by means of ports 0 f, with the passages to b, respectively.

Within the valve-chambers are located the disk-valves h z, mounted on the vertical valvestems k l, and seated, when in a normal position, on the seats m a, so as to close the ports 0 p and prevent the escape of the contents of the valve-chambers, the lower faces of the diskvalves h i being provided with elastic washers to effect a close joint in closing the cock.-

Each valve constitutes a combined disk and cylinder valve, -the cylindrical portions (indicated at 1' 8) serving to control the ports 6 f,

.leading from the passages a 1) into the respective valve-chambers c d. The lower disk-valve, h,is provided with an extension, t,on top,which is recessed at uto receive the lower end of the valve-stein l, which has a longitudinal play therein for the purpose of allowing the valves to be operated either independently of or in conjunction with each other, as more fully hereinafter set forth.

The upper valve-stem, 1, moves in and is guided by the recess '0 in the screweap Y,which tightly closes the top of the valve-casing, and the lower portionpf said stem moves in a guide, to, secured to the partition a. The lower valvestem is secured to a bar, b, extending across the interior of the discharge-nozzle, by means of a washer and screw, N, which prevents the screw-nozzle from being entirely screwed from the casing, and at the same time draws the lower valve down on its seat when closing the cook.

The cylindrical discharge B is provided with a female screw-thread, c, and is adapted to ride upon the male screw-thread on the outer portion of the lower end of the valve-casing in such manner as to operate the valves, as more fully hereinafter explained.

The valves are each acted on by springs c, by which the valves are held in a normal position, and automatically closed after being shifted; but such springs are not essential, as the pressure of water from within will effect this object when the screw-nozzle is screwed down to its normal position. The springs, however, are desirable, in order to assist the pressure of the water in closing the dischargeports.

The operation of my invention is as follows: The parts being in a normal or closed position, as seen in Fig. l, the disks of the respective valves will be closed upon their seats at n. The passage a being connected with a coldwater supply, and the passage b with a hotwater supply, upon turning or screwing up the discharge-nozzle B, so as to elevate the valve-stem 7r, the lower valve will be elevated from its seat, so as to permit the discharge of cold water alone, which will flow in through the port 0 and out through the port 0, passing through the openings in the disk and cylim drical valve h and r, the upper valve remaining closed during such primary movement. Upon further elevating the discharge-nozzle the upper valve-stem will be elevated, carrying with it the upper valve, permitting hot water to flow into the valve-chamber 0 through the ports f and p, passing through openings in disk and cylindrical valves 6 and s, where it will mix with the cold water flowing in through port 0. Upon still further elevating the valves the cylindrical portion of the lower valve will cover and close the port 0. cutting off the flow of cold water, while the cylindri cal portion of the upper valve will pass the port f, permitting hot water alone to pass out through the ports f, p, and o. p

A cook or valve as thus constructed has the means for actuating the valve wholly below the casing and on the discharge-month, and no projecting levers are required, the screwnozzle being neat and effective, and by its graduated movements efl'ectin g the entire control of the valve.

I have made the subject of a separate application filed on the same date with the present the combination, with the casing of a cook or faucet, of an adjustable screw-threaded nozzle fitting and adapted to ride upon the lower end of the screw-threaded casing, the nozzle being connected with the valve-stem carrying a valve for operating the same, and therefore do not here claim the said combination as broadly defined.

Having thus described my invention and its mode of operation, what Iclaim is- 1. The combination, in a cook or valve, of a valve-casing provided with two passages, communicating, respectively, with two valvechambers. and independent disk and tubular valves and valve-stems connected with mechanism whereby said valves may be operated independently of or in conjunction with each other to open the lower ports for the discharge of cold water, to open all of the ports for the discharge of mixed hot and cold water, or to close the lower induction-portend open the remaining ports to discharge hot water alone, substantially as specified.

2. The combination, with the two independent valves seated in separate valve-chambers. of the screw-nozzle connected with the lower valve-stem and adapted to ride up and down the lower screw-threaded end of the casing, for the purpose of operating the valve, substantially as specified.

In testimony that I claim the foregoing I have hereunto set my hand in the presence of the subscribing witnesses.

O. A. BLESSING.
